Answer:

r=3.25

Explanation:


16(1)/(2) = (22)/(7) (r + 2)


(33)/(2) = (22)/(7) (r + 2)


231 = 44(r + 2)


231 = 44r + 88


143 = 44r


3.25 = r

Answer:


r = 3 (1)/(4)

Explanation:

Given:

h = 2

U = 16,5


u = \pi(r + h)


(22)/(7) (r + 2) = 16.5

Multiply both sides of the equation by 7 to eliminate the fraction:


22(r + 2) = 115.5

Expand the brackets:


22r + 44 = 115.5

Collect like-terms:


22r = 71.5

Divide both sides of the equation by 22 to make r the subject:


r = 3.25 = 3 (1)/(4)
